1
00:00:08,433 --> 00:00:15,351
I grew up on a beach in an island
called Tasmania, a beautiful place.

2
00:00:16,440 --> 00:00:21,190
It gave me the opportunity to meet
and interact with incredible creatures,

3
00:00:21,681 --> 00:00:26,633
and it was where I developed
a deep connectivity with the ocean.

4
00:00:26,833 --> 00:00:30,610
Now, Tasmania is one of the most beautiful
islands on the planet.

5
00:00:30,610 --> 00:00:35,470
But 30 years ago, the city I grew up in
had a terrible problem.

6
00:00:35,470 --> 00:00:40,330
The ocean was polluted
with the outfall from heavy industry.

7
00:00:40,330 --> 00:00:42,495
There was a pulp and paper mill,

8
00:00:42,505 --> 00:00:46,806
a paint pigment plant
and a slaughterhouse among them.

9
00:00:47,216 --> 00:00:51,576
These were causing rashes on the bodies
of swimmers and surfers,

10
00:00:51,576 --> 00:00:55,568
and when you got out of the water,
you had sore red eyes.

11
00:00:55,888 --> 00:00:57,768
Burnie, at that time,

12
00:00:57,768 --> 00:01:01,728
had one of the highest incidence
of cancer in Australia.

13
00:01:02,388 --> 00:01:07,348
Following the lead of three generations
of journalists in my family,

14
00:01:07,578 --> 00:01:11,008
I made it my investigative
mission to uncover

15
00:01:11,008 --> 00:01:13,899
whether these industries
were, in fact, responsible


16
00:01:13,899 --> 00:01:16,119
for the illnesses we were seeing

17
00:01:16,119 --> 00:01:20,908
and also the poor state
of the ecosystem along the coastline.

18
00:01:21,669 --> 00:01:25,507
So, I got a laboratory to test
the waters around Burnie,

19
00:01:25,507 --> 00:01:29,459
and they found that the outfall
from the pulp and paper mill

20
00:01:29,459 --> 00:01:32,009
contained organic chlorines.

21
00:01:32,009 --> 00:01:37,161
And these had dangerous
cancer-causing dioxins.

22
00:01:37,831 --> 00:01:40,070
So, I put these findings
to the state government

23
00:01:40,070 --> 00:01:41,960
and the minister for the environment,

24
00:01:41,960 --> 00:01:43,590
and he admitted for the first time

25
00:01:43,590 --> 00:01:48,290
that they knew about these organic
chlorines and these dioxins

26
00:01:48,290 --> 00:01:51,801
and that they were dangerous,
but they hadn't informed the public.

27
00:01:52,023 --> 00:01:57,175
So, I published my stories
in the local newspaper,

28
00:01:57,901 --> 00:02:02,413
and it caused a storm of protest
across Australia.

29
00:02:04,283 --> 00:02:08,768
National papers declared Burnie
"Australia's dirtiest city."

30
00:02:08,768 --> 00:02:12,707
I wasn't very popular with our local
tourism authority, I can tell you.

31
00:02:13,180 --> 00:02:15,939
I was 20 years of age at the time.

32
00:02:17,529 --> 00:02:19,647
Shortly after those stories
were published,

33
00:02:19,647 --> 00:02:21,999
the industries started to close down,

34
00:02:22,589 --> 00:02:29,449
and today, Burnie has some
of the bluest water along the coastline,

35
00:02:29,449 --> 00:02:33,366
and the fish have returned
to the waters around the city.

36
00:02:34,248 --> 00:02:38,418
I learned then about
the power of the media.

37
00:02:42,349 --> 00:02:46,299
Now, as I developed my skills in the media

38
00:02:46,779 --> 00:02:50,229
through newspapers, radio and television,

39
00:02:50,629 --> 00:02:53,038
I also developed a passion for film.

40
00:02:53,038 --> 00:02:58,748
Film gave me the ability to tell stories
and to make documentaries

41
00:02:58,748 --> 00:03:03,698
that gave voice to silent creatures
like the worms from my childhood.

42
00:03:05,477 --> 00:03:08,613
But I also had a deep love

43
00:03:08,613 --> 00:03:13,833
for a particular species
that had consumed my time as a child,

44
00:03:13,833 --> 00:03:18,188
and that was the blue whale,
an immense creature,

45
00:03:18,194 --> 00:03:20,896
also incredibly shy.

46
00:03:21,686 --> 00:03:27,455
An opportunity came to film a documentary
off the south coast of Sri Lanka.

47
00:03:27,455 --> 00:03:30,144
It was the culmination, for me,
of a life's dream.

48
00:03:30,144 --> 00:03:34,154
Now, blue whales are the biggest
animals ever to have lived.

49
00:03:34,154 --> 00:03:36,014
They're bigger than any dinosaur.

50
00:03:36,014 --> 00:03:38,263
They grow up to about 37 meters long.

51
00:03:38,393 --> 00:03:40,943
They have a heart as big as a car.

52
00:03:40,943 --> 00:03:43,007
But they were hunted almost to extinction,

53
00:03:43,007 --> 00:03:46,357
and as a result,
they're extremely elusive.

54
00:03:46,357 --> 00:03:51,377
Trying to find them is like trying to find
a needle in a massive haystack.

55
00:03:52,083 --> 00:03:55,673
We went up and down the coastline
of Sri Lanka for weeks on end,

56
00:03:55,679 --> 00:03:57,695
searching for these whales.

57
00:03:57,695 --> 00:04:01,845
We would see a spout in the distance,
we'd head towards it.

58
00:04:02,055 --> 00:04:05,736
We would get our cameras
into our underwater housings.

59
00:04:05,967 --> 00:04:09,696
We'd get our teams into the water,
we'd move towards the whales,

60
00:04:10,038 --> 00:04:11,906
and then we would never see them again.


61
00:04:11,906 --> 00:04:16,080
And this happened day after day
after day after day.

62
00:04:16,080 --> 00:04:19,611
And if you want to know
what it's like to go crazy,

63
00:04:19,611 --> 00:04:22,580
look out into an open ocean,
empty open ocean

64
00:04:22,580 --> 00:04:25,930
for day after day after day after day.

65
00:04:25,930 --> 00:04:28,740
That's where coffee
became a big friend of mine.

66
00:04:29,769 --> 00:04:34,360
So, we searched
near an underwater seamount,

67
00:04:34,360 --> 00:04:35,995
and this is where krill gather

68
00:04:35,995 --> 00:04:38,075
because they're brought in
by the currents.

69
00:04:38,075 --> 00:04:41,445
And we knew the whales would head there
because they eat krill.

70
00:04:41,445 --> 00:04:43,055
We didn't find whales.

71
00:04:43,055 --> 00:04:47,185
What we found was something
very significant.

72
00:04:47,185 --> 00:04:50,424
It was a floating landfill of plastic.

73
00:04:50,851 --> 00:04:56,542
This was a massive slick of detritus
as far as the eye could see.

74
00:04:57,183 --> 00:05:03,574
It contained old fishing nets, bait boxes,
plastic bottles, used lighters,

75
00:05:03,574 --> 00:05:07,252
even unopened biscuits -
the wastage of humanity.

76
00:05:07,252 --> 00:05:09,613
It was absolutely dreadful.

77
00:05:09,743 --> 00:05:14,123
It was the sign of a coming tragedy.

78
00:05:14,613 --> 00:05:16,741
We didn't know that at the time.

79
00:05:16,918 --> 00:05:20,302
We kept looking for the whales
for three weeks,

80
00:05:20,302 --> 00:05:21,692
and our time finally ran out.

81
00:05:21,692 --> 00:05:25,652
We had to head back to port
because our visas were about to expire.

82
00:05:25,942 --> 00:05:29,241
But I'm an incredibly stubborn individual,

83
00:05:29,241 --> 00:05:34,732
and I hadn't come this far and worked
this hard to give up this easily,

84
00:05:34,732 --> 00:05:39,913
so I refused to allow the cameras
to be packed away.

85
00:05:40,281 --> 00:05:45,334
I refused to allow the dive tanks
to be put under the boat.

86
00:05:47,072 --> 00:05:50,763
I was going to exhaust
every possible moment we had on the water.

87
00:05:51,632 --> 00:05:57,073
Now, when someone yells "Whale,"
your adrenaline really spikes.

88
00:05:57,712 --> 00:06:01,792
Someone yelled "Whale,"
and my adrenaline shot through the roof.

89
00:06:02,723 --> 00:06:09,103
There, 100 meters
off our bow, was a spout -

90
00:06:09,573 --> 00:06:10,934
(Splashing sound)

91
00:06:10,934 --> 00:06:13,337
high and very visible.

92
00:06:14,898 --> 00:06:16,937
We cut the motors on the boat,

93
00:06:17,716 --> 00:06:19,564
we put the dive teams in the water,

94
00:06:19,564 --> 00:06:22,614
and the cameras,
and I got in with the crews,

95
00:06:22,614 --> 00:06:27,896
and we slowly finned over
towards what was a pot of whales.

96
00:06:27,896 --> 00:06:31,152
And as we got closer, we realized
this was a family of eight,

97
00:06:31,152 --> 00:06:34,904
and in this family
of eight whales was a juvenile.

98
00:06:34,904 --> 00:06:38,554
And when I say "juvenile,"
he was 15 meters long.

99
00:06:39,054 --> 00:06:42,021
And he was as curious of us
as we were of him,

100
00:06:42,021 --> 00:06:46,603
and with the big flick of his tail,
he dived incredibly deep and out of sight,

101
00:06:46,873 --> 00:06:51,264
and then, moments later, he came up
right between our cameras,

102
00:06:52,134 --> 00:06:54,344
and we had, for the first time,

103
00:06:54,344 --> 00:06:57,494
footage, under water,
on cinematic cameras,

104
00:06:57,494 --> 00:06:59,574
of a juvenile blue whale.

105
00:06:59,574 --> 00:07:02,583
It was a profound moment for us.

106
00:07:03,824 --> 00:07:07,155
As we were heading back to port
and I was reflecting on the shoot,

107
00:07:07,155 --> 00:07:11,259
I realized that these whales
were resting and probably feeding

108
00:07:11,259 --> 00:07:15,602
right near where we had filmed
this floating landfill of plastic.

109
00:07:15,602 --> 00:07:19,591
Now, whales, when they feed -
blue whales - they open their mouths,

110
00:07:19,591 --> 00:07:24,490
they suck in thousands of liters of water,
and they expel that water,

111
00:07:24,490 --> 00:07:28,323
leaving behind the krill
in their baleen, or their teeth.

112
00:07:28,332 --> 00:07:32,680
But whales can't tell the difference
between krill and plastic.

113
00:07:34,222 --> 00:07:40,402
The Sri Lankan expedition
was the start of an epic quest for us,

114
00:07:40,762 --> 00:07:43,443
but it posed more questions
than it answered:

115
00:07:43,443 --> 00:07:45,833
If whales were consuming plastic

116
00:07:45,833 --> 00:07:49,223
in a pristine environment
like the Indian Ocean,

117
00:07:49,223 --> 00:07:53,642
what was happening to marine life
in oceans in other parts of the planet?

118
00:07:54,081 --> 00:08:00,824
And if as we'd found out that 350 million
tons of plastic were being made that year,

119
00:08:00,824 --> 00:08:03,943
how much of that
was ending up in the oceans?

120
00:08:03,943 --> 00:08:08,013
And if marine life in oceans
around the world were consuming plastic,

121
00:08:08,014 --> 00:08:10,224
and we're at the top of the food chain,

122
00:08:10,224 --> 00:08:12,564
what did that mean for human health?

123
00:08:13,244 --> 00:08:18,464
Well, we gathered teams
and crews and scientists,

124
00:08:18,464 --> 00:08:23,220
and we traveled for four years
around the globe to 20 different locations

125
00:08:23,220 --> 00:08:27,624
to answer these questions
for our film "A Plastic Ocean."

126
00:08:28,163 --> 00:08:30,454
Our investigation was relentless.

127
00:08:30,454 --> 00:08:35,304
For example, we found
that 70% of plastic sinks.

128
00:08:36,044 --> 00:08:40,144
Now, what we'd seen then
was just the tip of the iceberg,

129
00:08:40,144 --> 00:08:44,444
so we hired a research vessel
and two submarines,

130
00:08:44,444 --> 00:08:46,124
and we went to the Mediterranean,

131
00:08:46,124 --> 00:08:48,583
and we traveled to the bottom 
of the Mediterranean,

132
00:08:48,583 --> 00:08:50,633
1,600 meters below the surface,

133
00:08:50,633 --> 00:08:55,033
to see what happened
to plastic in the absence of light,

134
00:08:55,033 --> 00:08:56,644
in the absence of oxygen.

135
00:08:57,524 --> 00:08:59,633
We traveled thousands of kilometers

136
00:08:59,633 --> 00:09:04,063
to the Pacific, to islands
where seabirds were ingesting plastic,

137
00:09:04,063 --> 00:09:05,703
mistaking it for food.

138
00:09:07,474 --> 00:09:13,723
One of the most powerful scenes
in the film is of a heroic little seabird

139
00:09:13,723 --> 00:09:15,424
called a shearwater.

140
00:09:15,424 --> 00:09:19,624
These birds, chicks,
were turning up dead in their hundreds

141
00:09:19,624 --> 00:09:22,164
on an island called Lord Howe Island.

142
00:09:23,194 --> 00:09:25,834
And when we opened
the stomachs of these birds,

143
00:09:25,834 --> 00:09:29,873
we found them filled with plastic.

144
00:09:30,513 --> 00:09:33,732
In one particular little chick,

145
00:09:34,112 --> 00:09:39,122
we found 272 pieces of plastic.

146
00:09:39,532 --> 00:09:44,384
That's equal to about 12 pizzas
if you were to eat them all at once

147
00:09:44,384 --> 00:09:46,394
and put them in your stomach.

148
00:09:46,394 --> 00:09:49,664
Can you imagine the pain
this animal was going through?

149
00:09:49,664 --> 00:09:54,504
As we opened other chicks,
we found a red bottle cap,

150
00:09:54,504 --> 00:09:55,884
and I realized at that moment

151
00:09:55,884 --> 00:10:01,573
that that bottle cap could have been
a bottle cap I threw away years earlier

152
00:10:01,573 --> 00:10:05,645
without understanding
the consequences of my actions.

153
00:10:06,244 --> 00:10:09,997
Now, if I'm a surfer, a diver
and an ocean explorer,

154
00:10:09,997 --> 00:10:14,994
and I didn't realize the consequences
of my actions to the natural world

155
00:10:14,994 --> 00:10:16,064
eight years ago,

156
00:10:16,064 --> 00:10:19,255
how could I expect anyone else
to understand theirs?

157
00:10:20,404 --> 00:10:27,243
We needed awareness, and "A Plastic Ocean"
would become the tool for that awareness.

158
00:10:30,401 --> 00:10:32,900
Now, scientists told us

159
00:10:32,900 --> 00:10:39,280
that we would dispose of
between 8 and 12 million tons of plastic

160
00:10:39,280 --> 00:10:42,229
into the world's oceans every year.

161
00:10:42,838 --> 00:10:45,920
How on earth did we allow that to happen?

162
00:10:46,748 --> 00:10:52,190
Well, the answer's simple: We were
told plastic would make our lives easier.

163
00:10:52,639 --> 00:10:55,060
We would no longer have to do
the washing up.

164
00:10:55,060 --> 00:10:57,270
It would keep our food fresher.

165
00:10:57,270 --> 00:11:01,174
It would protect our consumer products
like no other material before it.

166
00:11:01,174 --> 00:11:03,524
And in many ways, it did just that.

167
00:11:05,369 --> 00:11:10,189
But we were also told that plastic
could be used just once and thrown away.

168
00:11:10,970 --> 00:11:12,331
Think about that.

169
00:11:13,301 --> 00:11:16,485
Plastic is the most durable product
we have ever made.

170
00:11:16,485 --> 00:11:20,956
How can the most durable product
we've ever made be considered disposable?

171
00:11:21,556 --> 00:11:24,966
The answer is, "It can't. It isn't."

172
00:11:24,966 --> 00:11:30,715
Every piece of plastic ever made is still
on the Earth unless it's been burned.

173
00:11:33,253 --> 00:11:34,901
In the past decade,

174
00:11:35,241 --> 00:11:39,892
we have produced more plastic
than the entire century before that.

175
00:11:40,352 --> 00:11:41,371
Fifteen years ago,

176
00:11:41,371 --> 00:11:44,261
the United States'
Center for Decease Control

177
00:11:44,261 --> 00:11:50,082
released a study which showed
that more than 92% of all Americans

178
00:11:50,413 --> 00:11:54,679
contain chemicals related to plastic
in their blood and their urine.

179
00:11:54,930 --> 00:11:56,413
And more disturbing than that

180
00:11:56,413 --> 00:12:01,763
was that children between the ages
of 6 and 11 have twice as much.

181
00:12:02,433 --> 00:12:08,222
Now, plastic chemical like phthalates
and bisphenol As contain compounds

182
00:12:08,762 --> 00:12:13,822
which have estrogenic activity,
which mimic and sometimes block

183
00:12:13,832 --> 00:12:16,802
the natural hormonal
production of our bodies.

184
00:12:17,343 --> 00:12:22,702
Recent research shows that these
can cause endocrine disruptive decease,

185
00:12:22,702 --> 00:12:27,954
cancer, diabetes, fertility
and other reproductive issues.

186
00:12:29,102 --> 00:12:32,790
But plastic has become
an integral part of our society.

187
00:12:32,790 --> 00:12:34,122
It's a very useful tool.

188
00:12:34,122 --> 00:12:39,812
My cameras, my car, my computers -
all contain plastic components.

189
00:12:39,812 --> 00:12:44,170
But our habitual consumption
of single-use plastic

190
00:12:44,170 --> 00:12:47,420
is destroying life-giving environments.

191
00:12:47,420 --> 00:12:51,242
It's killing other species,
and it's polluting our food source.

192
00:12:51,672 --> 00:12:55,402
So, what will happen
if we don't stop production of plastic?

193
00:12:55,402 --> 00:12:59,582
Well, as of 2015,
we had produced, globally -

194
00:12:59,582 --> 00:13:03,222
since plastic production
has begun in the '50s -

195
00:13:03,222 --> 00:13:06,472
8.3 billion tons of plastic.

196
00:13:06,742 --> 00:13:08,742
8.3 billion tons.

197
00:13:09,551 --> 00:13:13,530
6.3 billion tons of that has become waste,

198
00:13:13,973 --> 00:13:19,902
and of that 6.3 billion tons of waste,
only 9% has been recycled.

199
00:13:21,111 --> 00:13:27,073
By 2050, our population will explode
to more than 9.8 billion people,

200
00:13:27,422 --> 00:13:32,611
and by then, we will be sending
12 billion tons of plastic to landfill

201
00:13:32,611 --> 00:13:34,142
and to the environment.

202
00:13:34,412 --> 00:13:35,932
It's staggering.

203
00:13:36,172 --> 00:13:37,742
So, what's the solution?

204
00:13:38,832 --> 00:13:42,283
Well, we need to stop our addiction
to single-use plastic.

205
00:13:42,283 --> 00:13:45,702
We need to move to a zero-waste society.

206
00:13:46,943 --> 00:13:52,061
We need to change the very social
and financial paradigms

207
00:13:52,061 --> 00:13:56,146
that consider single-use plastic
a useful resource.

208
00:13:56,615 --> 00:14:00,496
We need a multifaceted approach
to this problem,

209
00:14:00,496 --> 00:14:04,594
with input from governments, retailers,
manufacturers, consumers.

210
00:14:04,856 --> 00:14:07,866
And we need to integrate new ideas,

211
00:14:07,866 --> 00:14:12,086
like new legislation, circular economies

212
00:14:12,086 --> 00:14:16,665
and cradle-to-grave responsibility
for manufacturers and retailers.

213
00:14:16,665 --> 00:14:17,887
And as consumers,

214
00:14:17,887 --> 00:14:22,097
each one of us needs to be smarter
about the choices we make.

215
00:14:22,097 --> 00:14:24,938
We all need to rethink plastic.

216
00:14:25,207 --> 00:14:27,027
So, how do we do that?

217
00:14:28,017 --> 00:14:31,127
Well, we stop buying
single-use plastics, to start with.

218
00:14:32,036 --> 00:14:35,537
When I'm at home, and I have a drink,
I don't need to use a straw.

219
00:14:35,548 --> 00:14:38,248
So why do I need a straw
when I go to a restaurant?

220
00:14:38,467 --> 00:14:39,696
I don't.

221
00:14:40,226 --> 00:14:46,788
Why would I spend up to 2,000% more
buying water in a plastic bottle

222
00:14:46,788 --> 00:14:51,526
when it costs me so much less
to refill a steel container from the tap,

223
00:14:51,526 --> 00:14:53,518
and it's quite often healthier?

224
00:14:53,518 --> 00:14:54,887
It makes no sense.

225
00:14:55,917 --> 00:15:00,498
Take a bag with you, a reusable bag,
when you go shopping.

226
00:15:00,498 --> 00:15:06,178
And when you get to the supermarket
or the market, call the manager over.

227
00:15:06,417 --> 00:15:10,980
At the checkout, unwrap all the plastic
from all of those fruits and vegetables

228
00:15:10,980 --> 00:15:13,880
that have been individually wrapped
with this plastic stuff,

229
00:15:13,880 --> 00:15:15,236
and give it to the manager,

230
00:15:15,236 --> 00:15:17,296
back to the supermarket,
back to the market,

231
00:15:17,296 --> 00:15:19,157
and tell them to dispose of it properly

232
00:15:19,157 --> 00:15:22,323
because you don't want to have
the responsibility of taking it home

233
00:15:22,323 --> 00:15:24,543
and having to do that anyway.

234
00:15:26,829 --> 00:15:29,966
But more importantly, we need to go back.

235
00:15:29,966 --> 00:15:36,148
We need to understand the systems
that sustain life on planet Earth,

236
00:15:36,938 --> 00:15:39,126
like the bird and the worm.

237
00:15:39,126 --> 00:15:41,266
The bird wasn't committing murder.

238
00:15:41,266 --> 00:15:45,485
They're part of a greater ecological,
environmental system

239
00:15:45,485 --> 00:15:47,196
which sustains life on Earth.

240
00:15:47,196 --> 00:15:48,378
I know that now.

241
00:15:48,378 --> 00:15:50,938
I didn't when I was five years of age.

242
00:15:50,938 --> 00:15:53,118
Just like eight years ago,

243
00:15:53,118 --> 00:15:58,029
I had no idea that by throwing
my plastic products into the rubbish bin,

244
00:15:58,029 --> 00:16:00,026
I was damaging the environment,

245
00:16:00,027 --> 00:16:02,357
and I was polluting the food chain.

246
00:16:04,197 --> 00:16:07,387
Awareness is a very powerful tool.

247
00:16:07,756 --> 00:16:09,278
As I say in the film,

248
00:16:09,278 --> 00:16:14,387
"With knowing comes caring,
and with caring comes change."

249
00:16:14,927 --> 00:16:17,486
And I'd like to leave you
with this last thought:

250
00:16:18,638 --> 00:16:22,198
Change starts with each
and every one of you.

251
00:16:23,536 --> 00:16:29,017
There is a need to change,
and when that need arises, it's right now.

252
00:16:29,742 --> 00:16:32,328
So, we all need to start change

253
00:16:32,328 --> 00:16:36,598
for our future, for ourselves
and for our children.

254
00:16:36,847 --> 00:16:38,386
Thank you very much.

255
00:16:38,386 --> 00:16:40,064
(Applause)
